9.2 Sensor types
MULTICAL
401 can be supplied with two different sensor sets, both with 1.5 m or 3.0 m cable. Below is stated
the most important characteristics for both types (see data sheet 5810-337 for further information on sensor sets
and sensor pockets):
Type 66-
Sensor connection
Pt100 (Kamstrup does not supply Pt100 sensors) V
Pt500 W
Pt500 sensors
Pocket sensor with 1.5 m cable A
Pocket sensor with 3.0 m cable B
Short direct sensor with 1.5 m cable F
Short direct sensor with 3.0 m cable G
9.3 Pt500 sensor set for pockets
Pt500 cable sensor based on a 2-wire silicone cable and closed by a stainless steel tube with a diameter of
5.8 mm protecting the sensor element.
The steel tube is fitted in a sensor pocket that has an inside diameter of 6 mm and an outside diameter of
8 mm. The sensor pockets are supplied with an R½ (conical ½”) connection in stainless steel in lengths of 65,
90, and 140 mm. The sensor design with separate pocket means that the sensors can be replaced without the
water being shut off. Additionally, the large selection of pocket lengths means that the sensors can be fitted in all
pipe sizes.

The stainless steel pockets can be applied when mounting in PN25 systems!
The plastic tube on the sensor
cable is placed in front of the seal
screw, this can be tightened
easily by hand before sealing.
